Raymond Braine is considered the country’s best player during the interwar period. He was suspended for the most important tournament, the 1930 World Cup, due to non-compliance with the amateur statute. He owned a bar which was not allowed for a football player as he, indirectly, generated income from his fame. This also proved costly for the RBFA, as he was truly missed during that World Cup. Braine became the first Belgian professional player to move abroad. He was an excellent player for Sparta Prague.
